How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Caladium ‘Red Flash’
Caladium ‘Red Flash’ is a large fancy-leaf Caladium with broad heart-shaped leaves. The larger leaves carry a deep red centre, green margins and pale speckles.
In warmth, it sends up leaf after leaf from the tuber, then rests once the foliage declines.

- Wide green margins
- Pale to pink speckling

How Caladium ‘Red Flash’ grows
Larger leaves need a warm, well-rooted tuber. Warmth, steady watering and an airy mix help the larger leaves develop properly. When the leaves decline, the tuber can rest.
Caladium ‘Red Flash’ care for larger leaves
- Light: Give bright filtered light. It can handle brighter conditions after acclimation, but protect it from hot glass and harsh midday sun.
- Watering: Water thoroughly once the upper layer starts to dry. Let excess water drain fully.
- Substrate: Use a fertile but open mix with bark or fibre plus pumice or perlite.
- Warmth: Keep around 20–30 °C while leaves are forming.
- Humidity: Maintain steady humidity and avoid hot dry airflow.
- Feeding: Feed lightly but regularly while large leaves are forming.
- Pot stability: Use a stable pot with drainage holes.
- Propagation: Divide only mature firm tubers with visible buds or eyes. Let cut surfaces dry before planting.
- Rest: Reduce watering after seasonal decline and keep the resting tuber warm and dry.
- Outdoor use: In warm weather, a sheltered shaded outdoor position can suit the plant after acclimation.
Caladium ‘Red Flash’ flowers
If a flower appears, remove it after fading so the tuber can keep more energy for leaves.
Caladium ‘Red Flash’ drooping, scorch and tuber issues
- Large leaves drooping: Check cold mix, saturated roots, underwatering during heat or recent transport stress.
- Brown sun marks: Too much direct sun or heat near glass.
- Soft petioles: Give brighter filtered light and check that the mix is not staying wet and dense.
- Small new leaves: Increase warmth and filtered light, especially on smaller tubers.
- Soft tuber areas: Excess water in cool conditions.
- Pests: Inspect the undersides of large leaves and around petiole bases.
- Seasonal yellowing: A firm tuber is a good sign; reduce watering gradually as the plant rests.
Caladium ‘Red Flash’ safety
Caladium ‘Red Flash’ contains insoluble calcium oxalate crystals. If eaten or nibbled, it may irritate the mouth and throat. Keep it away from pets and children.
Caladium ‘Red Flash’ cultivar background
